What is the rock cycle?

Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through processes like weathering, erosion, sedimentation, and metamorphism.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles, often in layers.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are subjected to heat and pressure, causing physical and chemical changes.

Front

What does the Law of Superposition state?

Back

The Law of Superposition states that in undisturbed layers of rock, younger rocks lie above older rocks.

Front

What is the Law of Cross-Cutting Relationships?

Back

The Law of Cross-Cutting Relationships states that a geological feature (like a fault or intrusion) is younger than any rock layer it cuts through.

Front

How does weathering contribute to the rock cycle?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.

Front

What role do plant roots play in soil erosion?

Back

Plant roots help prevent soil erosion by holding the soil in place and binding it to the land.

Front

What is coal classified as?

Back

Coal is classified as a sedimentary rock formed from the remains of plants and animals buried under sediments.
